History of the Wensleydale
The mating of a Dishley Leicester ram with a Teeswater ewe in 1838 produced the famous ram 'Blue Cap' who was the founding sire of the Wensleydale breed. He was a striking ram, with blue pigmentation on his head and ears that is now the hallmark of the breed, great size (203 kg as a two-shear) and wool of distinctive quality. The modern Wensleydale has inherited these qualities. It is a large sheep with long-stapled, lustrous wool that falls in long ringlets almost to ground level in unshorn sheep. The breed has a quality known as 'central checking’ that prevents the formation of kemp in the fleece.
The Wensleydale is a very large longwool sheep, described by the British Meat and Livestock Commission as "probably the heaviest of all our indigenous breeds." It is a visually striking sheep with considerable presence. It has a bold and alert carriage which is accentuated by its broad, level back and heavy muscling in the hindquarters. It has a distinctive deep blue head and ears, which should be clean except for a well developed forelock of wool. Both sexes are polled.
